BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to the field of corn breeding.In particular, the invention relates to corn seed and plants of thevariety designated CV951414, and derivatives and tissue culturesthereof.

2. Description of Related Art

The goal of field crop breeding is to combine various desirable traitsin a single variety/hybrid. Such desirable traits include greater yield,better stalks, better roots, resistance to insecticides, herbicides,pests, and disease, tolerance to heat and drought, reduced time to cropmaturity, better agronomic quality, higher nutritional value, anduniformity in germination times, stand establishment, growth rate,maturity, and fruit size.

Breeding techniques take advantage of a plant's method of pollination.There are two general methods of pollination: a plant self-pollinates ifpollen from one flower is transferred to the same or another flower ofthe same plant. A plant cross-pollinates if pollen comes to it from aflower on a different plant.

Corn plants (Zea mays L.) can be bred by both self-pollination andcross-pollination. Both types of pollination involve the corn plant'sflowers. Corn has separate male and female flowers on the same plant,located on the tassel and the ear, respectively. Natural pollinationoccurs in corn when wind blows pollen from the tassels to the silks thatprotrude from the tops of the ear shoot.

Plants that have been self-pollinated and selected for type over manygenerations become homozygous at almost all gene loci and produce auniform population of true breeding progeny, a homozygous plant. A crossbetween two such homozygous plants produces a uniform population ofhybrid plants that are heterozygous for many gene loci. Conversely, across of two plants each heterozygous at a number of loci produces apopulation of hybrid plants that differ genetically and are not uniform.The resulting non-uniformity makes performance unpredictable.

The development of uniform corn plant hybrids requires the developmentof homozygous inbred plants, the crossing of these inbred plants, andthe evaluation of the crosses. Pedigree breeding and recurrent selectionare examples of breeding methods used to develop inbred plants frombreeding populations. Those breeding methods combine the geneticbackgrounds from two or more inbred plants or various other broad-basedsources into breeding pools from which new inbred plants are developedby selfing and selection of desired phenotypes. The new inbreds arecrossed with other inbred plants and the hybrids from these crosses areevaluated to determine which of those have commercial potential.

North American farmers plant tens of millions of acres of corn at thepresent time and there are extensive national and internationalcommercial corn breeding programs. A continuing goal of these cornbreeding programs is to develop corn hybrids that are based on stableinbred plants and have one or more desirable characteristics. Toaccomplish this goal, the corn breeder must select and develop superiorinbred parental plants.

SUMMARY OF THE INVENTION

In one aspect, the present invention provides a corn plant of thevariety designated CV951414. Also provided are corn plants having allthe physiological and morphological characteristics of the inbred cornvariety CV951414. The inbred corn plant of the invention may furthercomprise, or have, a cytoplasmic or nuclear factor that is capable ofconferring male sterility or otherwise preventing self-pollination, suchas by self-incompatibility. Parts of the corn plant of the presentinvention are also provided, for example, pollen obtained from an inbredplant and an ovule of the inbred plant.

The invention also concerns seed of the inbred corn variety CV951414.The inbred corn seed of the invention may be provided as an essentiallyhomogeneous population of inbred corn seed of the variety designatedCV951414. Essentially homogeneous populations of inbred seed aregenerally free from substantial numbers of other seed. Therefore, in thepractice of the present invention, inbred seed generally forms at leastabout 97% of the total seed. The population of inbred corn seed of theinvention may be particularly defined as being essentially free fromhybrid seed. The inbred seed population may be separately grown toprovide an essentially homogeneous population of inbred corn plantsdesignated CV951414.

In another aspect of the invention, a plant of corn variety CV951414comprising an added heritable trait is provided. The heritable trait maycomprise a genetic locus that is a dominant or recessive allele. In oneembodiment of the invention, a plant of corn variety CV951414 comprisinga single locus conversion in particular is provided. In specificembodiments of the invention, an added genetic locus confers one or moretraits such as, for example, male sterility, herbicide tolerance, insectresistance, disease resistance, waxy starch, modified fatty acidmetabolism, modified phytic acid metabolism, modified carbohydratemetabolism and modified protein metabolism. The trait may be, forexample, conferred by a naturally occurring maize gene introduced intothe genome of the variety by backcrossing, a natural or inducedmutation, or a transgene introduced through genetic transformationtechniques. When introduced through transformation, a genetic locus maycomprise one or more transgenes integrated at a single chromosomallocation.

In yet another aspect of the invention, an inbred corn plant of thevariety designated CV951414 is provided, wherein acytoplasmically-inherited trait has been introduced into said inbredplant. Such cytoplasmically-inherited traits are passed to progenythrough the female parent in a particular cross. An exemplarycytoplasmically-inherited trait is the male sterility trait.Cytoplasmic-male sterility (CMS) is a pollen abortion phenomenondetermined by the interaction between the genes in the cytoplasm and thenucleus. Alteration in the mitochondrial genome and the lack of restorergenes in the nucleus will lead to pollen abortion. With either a normalcytoplasm or the presence of restorer gene(s) in the nucleus, the plantwill produce pollen normally. A CMS plant can be pollinated by amaintainer version of the same variety, which has a normal cytoplasm butlacks the restorer gene(s) in the nucleus, and continue to be malesterile in the next generation. The male fertility of a CMS plant can berestored by a restorer version of the same variety, which must have therestorer gene(s) in the nucleus. With the restorer gene(s) in thenucleus, the offspring of the male-sterile plant can produce normalpollen grains and propagate. A cytoplasmically inherited trait may be anaturally occurring maize trait or a trait introduced through genetictransformation techniques.

In another aspect of the invention, a tissue culture of regenerablecells of a plant of variety CV951414 is provided. The tissue culturewill preferably be capable of regenerating plants capable of expressingall of the physiological and morphological characteristics of thevariety, and of regenerating plants having substantially the samegenotype as other plants of the variety. Examples of some of thephysiological and morphological characteristics of the variety CV951414include characteristics related to yield, maturity, and kernel quality,each of which is specifically disclosed herein. The regenerable cells insuch tissue cultures will preferably be derived from embryos,meristematic cells, immature tassels, microspores, pollen, leaves,anthers, roots, root tips, silk, flowers, kernels, ears, cobs, husks, orstalks, or from callus or protoplasts derived from those tissues. Stillfurther, the present invention provides corn plants regenerated from thetissue cultures of the invention, the plants having all thephysiological and morphological characteristics of variety CV951414.

In yet another aspect of the invention, processes are provided forproducing corn seeds or plants, which processes generally comprisecrossing a first parent corn plant with a second parent corn plant,wherein at least one of the first or second parent corn plants is aplant of the variety designated CV951414. These processes may be furtherexemplified as processes for preparing hybrid corn seed or plants,wherein a first inbred corn plant is crossed with a second corn plant ofa different, distinct variety to provide a hybrid that has, as one ofits parents, the inbred corn plant variety CV951414. In these processes,crossing will result in the production of seed. The seed productionoccurs regardless of whether the seed is collected or not.

In one embodiment of the invention, the first step in “crossing”comprises planting, preferably in pollinating proximity, seeds of afirst and second parent corn plant, and preferably, seeds of a firstinbred corn plant and a second, distinct inbred corn plant. Where theplants are not in pollinating proximity, pollination can nevertheless beaccomplished by transferring a pollen or tassel bag from one plant tothe other as described below.

A second step comprises cultivating or growing the seeds of said firstand second parent corn plants into plants that bear flowers (corn bearsboth male flowers (tassels) and female flowers (silks) in separateanatomical structures on the same plant). A third step comprisespreventing self-pollination of the plants, i.e., preventing the silks ofa plant from being fertilized by any plant of the same variety,including the same plant. This is preferably done by emasculating themale flowers of the first or second parent corn plant, (i.e., treatingor manipulating the flowers so as to prevent pollen production, in orderto produce an emasculated parent corn plant). Self-incompatibilitysystems may also be used in some hybrid crops for the same purpose.Self-incompatible plants still shed viable pollen and can pollinateplants of other varieties but are incapable of pollinating themselves orother plants of the same variety.

A fourth step may comprise allowing cross-pollination to occur betweenthe first and second parent corn plants. When the plants are not inpollinating proximity, this is done by placing a bag, usually paper orglassine, over the tassels of the first plant and another bag over thesilks of the incipient ear on the second plant. The bags are left inplace for at least 24 hours. Since pollen is viable for less than 24hours, this assures that the silks are not pollinated from other pollensources, that any stray pollen on the tassels of the first plant isdead, and that the only pollen transferred comes from the first plant.The pollen bag over the tassel of the first plant is then shakenvigorously to enhance release of pollen from the tassels, and the shootbag is removed from the silks of the incipient ear on the second plant.Finally, the pollen bag is removed from the tassel of the first plantand is placed over the silks of the incipient ear of the second plant,shaken again and left in place. Yet another step comprises harvestingthe seeds from at least one of the parent corn plants. The harvestedseed can be grown to produce a corn plant or hybrid corn plant.

The present invention also provides corn seed and plants produced by aprocess that comprises crossing a first parent corn plant with a secondparent corn plant, wherein at least one of the first or second parentcorn plants is a plant of the variety designated CV951414. In oneembodiment of the invention, corn seed and plants produced by theprocess are first generation (F₁) hybrid corn seed and plants producedby crossing an inbred in accordance with the invention with another,distinct inbred. The present invention further contemplates seed of anF₁ hybrid corn plant. Therefore, certain exemplary embodiments of theinvention provide an F₁ hybrid corn plant and seed thereof.

In still yet another aspect of the invention, the genetic complement ofthe corn plant variety designated CV951414 is provided. The phrase“genetic complement” is used to refer to the aggregate of nucleotidesequences, the expression of which sequences defines the phenotype of,in the present case, a corn plant, or a cell or tissue of that plant. Agenetic complement thus represents the genetic make up of an inbredcell, tissue or plant, and a hybrid genetic complement represents thegenetic make up of a hybrid cell, tissue or plant. The invention thusprovides corn plant cells that have a genetic complement in accordancewith the inbred corn plant cells disclosed herein, and plants, seeds anddiploid plants containing such cells.

Plant genetic complements may be assessed by genetic marker profiles,and by the expression of phenotypic traits that are characteristic ofthe expression of the genetic complement, e.g., isozyme typing profiles.It is understood that variety CV951414 could be identified by any of themany well known techniques such as, for example, Simple Sequence LengthPolymorphisms (SSLPs) (Williams et al., Nucleic Acids Res.,18:6531-6535, 1990), Randomly Amplified Polymorphic DNAs (RAPDs), DNAAmplification Fingerprinting (DAF), Sequence Characterized AmplifiedRegions (SCARs), Arbitrary Primed Polymerase Chain Reaction (AP-PCR),Amplified Fragment Length Polymorphisms (AFLPs) (EP 534 858,specifically incorporated herein by reference in its entirety), andSingle Nucleotide Polymorphisms (SNPs) (Wang et al., Science,280:1077-1082, 1998).

In still yet another aspect, the present invention provides hybridgenetic complements, as represented by corn plant cells, tissues,plants, and seeds, formed by the combination of a haploid geneticcomplement of an inbred corn plant of the invention with a haploidgenetic complement of a second corn plant, preferably, another, distinctinbred corn plant. In another aspect, the present invention provides acorn plant regenerated from a tissue culture that comprises a hybridgenetic complement of this invention.

In still yet another aspect, the present invention provides a method ofproducing an inbred corn plant derived from the corn variety CV951414,the method comprising the steps of: (a) preparing a progeny plantderived from corn variety CV951414, wherein said preparing comprisescrossing a plant of the corn variety CV951414 with a second corn plant;(b) crossing the progeny plant with itself or a second plant to producea seed of a progeny plant of a subsequent generation; (c) growing aprogeny plant of a subsequent generation from said seed of a progenyplant of a subsequent generation and crossing the progeny plant of asubsequent generation with itself or a second plant; and (d) repeatingthe steps for an additional 3-10 generations to produce an inbred cornplant derived from the corn variety CV951414. In the method, it may bedesirable to select particular plants resulting from step (c) forcontinued crossing according to steps (b) and (c). By selecting plantshaving one or more desirable traits, an inbred corn plant derived fromthe corn variety CV951414 is obtained which possesses some of thedesirable traits of corn variety CV951414 as well potentially otherselected traits.

IV. Further Embodiments of the Invention

In certain further aspects, the invention provides plants modified toinclude at least a first desired heritable trait. Such plants may, inone embodiment, be developed by a plant breeding technique calledbackcrossing, wherein essentially all of the morphological andphysiological characteristics of a variety are recovered in addition toa genetic locus transferred into the plant via the backcrossingtechnique. By essentially all of the morphological and physiologicalcharacteristics, it is meant that the characteristics of a plant arerecovered that are otherwise present when compared in the sameenvironment, other than an occasional variant trait that might ariseduring backcrossing or direct introduction of a transgene. It isunderstood that a locus introduced by backcrossing may or may not betransgenic in origin, and thus the term backcrossing specificallyincludes backcrossing to introduce loci that were created by genetictransformation.

Backcrossing methods can be used with the present invention to improveor introduce a trait into a variety. The term backcrossing as usedherein refers to the repeated crossing of a hybrid progeny back to oneof the parental corn plants. The parental corn plant which contributesthe locus or loci for the desired trait is termed the nonrecurrent ordonor parent. This terminology refers to the fact that the nonrecurrentparent is used one time in the backcross protocol and therefore does notrecur.

The parental corn plant to which the locus or loci from the nonrecurrentparent are transferred is known as the recurrent parent as it is usedfor several rounds in the backcrossing protocol (Poehlman et al., In:Breeding Field Crops, 4^(th) Ed., Iowa State University Press, Ames,Iowa, 132-155; 321-344, 1995; Fehr, Principles of Cultivar Development,1:360-376, 1987; Sprague and Dudley, In: Corn and Corn Improvement,3^(rd) Ed., Crop Science of America, Inc.; Soil Science of America,Inc., Wisconsin. 881-883; 901-918, 1988). In a typical backcrossprotocol, the original parent of interest (recurrent parent) is crossedto a second variety (nonrecurrent parent) that carries the genetic locusof interest to be transferred. The resulting progeny from this cross arethen crossed again to the recurrent parent and the process is repeateduntil a corn plant is obtained wherein essentially all of the desiredmorphological and physiological characteristics of the recurrent parentare recovered in the converted plant, in addition to the transferredlocus from the nonrecurrent parent. The backcross process may beaccelerated by the use of genetic markers, such as SSR, RFLP, SNP orAFLP markers to identify plants with the greatest genetic complementfrom the recurrent parent.

The selection of a suitable recurrent parent is an important step for asuccessful backcrossing procedure. The goal of a backcross protocol isto add or substitute one or more new traits in the original variety andprogeny therefrom. To accomplish this, a genetic locus of the recurrentparent is modified or substituted with the desired locus from thenonrecurrent parent, while retaining essentially all of the rest of thedesired genetic, and therefore the desired physiological andmorphological constitution of the original plant. The choice of theparticular nonrecurrent parent will depend on the purpose of thebackcross; one of the major purposes is to add some commerciallydesirable, agronomically important trait to the plant. The exactbackcrossing protocol will depend on the characteristic or trait beingaltered to determine an appropriate testing protocol. Althoughbackcrossing methods are simplified when the characteristic beingtransferred is a dominant allele, a recessive allele may also betransferred. In this instance it may be necessary to introduce a test ofthe progeny to determine if the desired characteristic has beensuccessfully transferred.

Many traits have been identified that are not regularly selected for inthe development of a new variety but that can be improved bybackcrossing techniques. A genetic locus conferring the traits may ormay not be transgenic. Examples of such traits known to those of skillin the art include, but are not limited to, male sterility, waxy starch,herbicide resistance, resistance for bacterial, fungal, or viraldisease, insect resistance, male fertility and enhanced nutritionalquality. These genes are generally inherited through the nucleus, butmay be inherited through the cytoplasm. Some known exceptions to thisare genes for male sterility, some of which are inheritedcytoplasmically, but still act as a single locus trait.

Direct selection may be applied where a genetic locus acts as a dominanttrait. An example of a dominant trait is the herbicide resistance trait.For this selection process, the progeny of the initial cross are sprayedwith the herbicide prior to the backcrossing. The spraying eliminatesany plants which do not have the desired herbicide resistancecharacteristic, and only those plants which have the herbicideresistance gene are used in the subsequent backcross. This process isthen repeated for all additional backcross generations.

Many useful traits are those which are introduced by genetictransformation techniques. Methods for the genetic transformation ofcorn are known to those of skill in the art. For example, methods whichhave been described for the genetic transformation of corn includeelectroporation (U.S. Pat. No. 5,384,253), electrotransformation (U.S.Pat. No. 5,371,003), microprojectile bombardment (U.S. Pat. Nos.5,550,318; 5,736,369, 5,538,880; and PCT Publication WO 95/06128),Agrobacterium-mediated transformation (U.S. Pat. No. 5,591,616 and E.P.Publication EP672752), direct DNA uptake transformation of protoplasts(Omirulleh et al., Plant Mol. Biol., 21(3):415-428, 1993) and siliconcarbide fiber-mediated transformation (U.S. Pat. No. 5,302,532 and U.S.Pat. No. 5,464,765).

It is understood to those of skill in the art that a transgene need notbe directly transformed into a plant, as techniques for the productionof stably transformed corn plants that pass single loci to progeny byMendelian inheritance are well known in the art. Such loci may thereforebe passed from parent plant to progeny plants by standard plant breedingtechniques that are well known in the art. Non-limiting examples oftraits that may be introduced into a corn plant according to specificembodiments of the invention are provided below.

A. Male Sterility

Examples of genes conferring male sterility include those disclosed inU.S. Pat. Nos. 3,861,709, 3,710,511, 4,654,465, 5,625,132, and4,727,219, each of the disclosures of which are specificallyincorporated herein by reference in their entirety. The use ofherbicide-inducible male sterility genes is described in U.S. Pat. No.6,762,344. Male sterility genes can increase the efficiency with whichhybrids are made, in that they eliminate the need to physicallyemasculate the corn plant used as a female in a given cross.

Where one desires to employ male-sterility systems with a corn plant inaccordance with the invention, it may be beneficial to also utilize oneor more male-fertility restorer genes. For example, where cytoplasmicmale sterility (CMS) is used, hybrid seed production requires threeinbred lines: (1) a cytoplasmically male-sterile line having a CMScytoplasm; (2) a fertile inbred with normal cytoplasm, which is isogenicwith the CMS line for nuclear genes (“maintainer line”); and (3) adistinct, fertile inbred with normal cytoplasm, carrying a fertilityrestoring gene (“restorer” line). The CMS line is propagated bypollination with the maintainer line, with all of the progeny being malesterile, as the CMS cytoplasm is derived from the female parent. Thesemale sterile plants can then be efficiently employed as the femaleparent in hybrid crosses with the restorer line, without the need forphysical emasculation of the male reproductive parts of the femaleparent.

The presence of a male-fertility restorer gene results in the productionof fully fertile F₁ hybrid progeny. If no restorer gene is present inthe male parent, male-sterile hybrids are obtained. Such hybrids areuseful where the vegetative tissue of the corn plant is utilized, e.g.,for silage, but in most cases, the seeds will be deemed the mostvaluable portion of the crop, so fertility of the hybrids in these cropsmust be restored. Therefore, one aspect of the current inventionconcerns plants of the corn variety CV951414 comprising a genetic locuscapable of restoring male fertility in an otherwise male-sterile plant.Examples of male-sterility genes and corresponding restorers which couldbe employed with the plants of the invention are well known to those ofskill in the art of plant breeding and are disclosed in, for instance,U.S. Pat. Nos. 5,530,191; 5,689,041; 5,741,684; and 5,684,242, thedisclosures of which are each specifically incorporated herein byreference in their entirety.

B. Herbicide Resistance

Numerous herbicide resistance genes are known and may be employed withthe invention. An example is a gene conferring resistance to a herbicidethat inhibits the growing point or meristem, such as an imidazalinone ora sulfonylurea. Exemplary genes in this category code for mutant ALS andAHAS enzyme as described, for example, by Lee et al., EMBO J., 7:1241,1988; Gleen et al., Plant Molec. Biology, 18:1185-1187, 1992; and Mikiet al., Theor. Appl. Genet., 80:449, 1990.

Resistance genes for glyphosate (resistance conferred by mutant5-enolpyruvl-3 phosphikimate synthase (EPSPS) and aroA genes,respectively), and hygromycin B phosphotransferase, and to otherphosphono compounds such as glufosinate (phosphinothricin acetyltransferase (PAT) and Streptomyces hygroscopicus phosphinothricin-acetyltransferase (bar) genes) may also be used. See, for example, U.S. Pat.No. 4,940,835 to Shah, et al., which discloses the nucleotide sequenceof a form of EPSPS which can confer glyphosate resistance. Examples ofspecific EPSPS transformation events conferring glyphosate resistanceare provided by U.S. Pat. No. 6,040,497.

A DNA molecule encoding a mutant aroA gene can be obtained under ATCCaccession number 39256, and the nucleotide sequence of the mutant geneis disclosed in U.S. Pat. No. 4,769,061 to Comai. A hygromycin Bphosphotransferase gene from E. coli which confers resistance toglyphosate in tobacco callus and plants is described in Penaloza-Vazquezet al., Plant Cell Reports, 14:482-487, 1995. European patentapplication No. 0 333 033 to Kumada et al., and U.S. Pat. No. 4,975,374to Goodman et al., disclose nucleotide sequences of glutamine synthetasegenes which confer resistance to herbicides such as L-phosphinothricin.The nucleotide sequence of a phosphinothricin-acetyltransferase gene isprovided in European application No. 0 242 246 to Leemans et al. DeGreefet al. (Biotechnology, 7:61, 1989), describe the production oftransgenic plants that express chimeric bar genes coding forphosphinothricin acetyl transferase activity. Exemplary of genesconferring resistance to phenoxy propionic acids and cycloshexones, suchas sethoxydim and haloxyfop are the Acct-S1, Accl-S2 and Acct-S3 genesdescribed by Marshall et al., (Theor. Appl. Genet., 83:4:35, 1992).

Genes are also known conferring resistance to a herbicide that inhibitsphotosynthesis, such as a triazine (psbA and gs+ genes) and abenzonitrile (nitrilase gene). Przibila et al., (Plant Cell, 3:169,1991), describe the transformation of Chlamydomonas with plasmidsencoding mutant psbA genes. Nucleotide sequences for nitrilase genes aredisclosed in U.S. Pat. No. 4,810,648 to Stalker, and DNA moleculescontaining these genes are available under ATCC Accession Nos. 53435,67441, and 67442. Cloning and expression of DNA coding for a glutathioneS-transferase is described by Hayes et al., (Biochem. J., 285(Pt1):173-180, 1992). Protoporphyrinogen oxidase (PPO) is the target of thePPO-inhibitor class of herbicides; a PPO-inhibitor resistant PPO genewas recently identified in Amaranthus tuberculatus (Patzoldt et al.,PNAS, 103(33):12329-2334, 2006). The herbicide methyl viologen inhibitsCO₂ assimilation. Foyer et al. (Plant Physio.l, 109:1047-1057, 1995)describe a plant overexpressing glutathione reductase (GR) which isresistant to methyl viologen treatment.

Siminszky (Phytochemistry Reviews, 5:445-458, 2006) describes plantcytochrome P450-mediated detoxification of multiple, chemicallyunrelated classes of herbicides.

Other examples of herbicide resistance have been described, forinstance, in U.S. Pat. Nos. 6,803,501; 6,448,476; 6,248,876; 6,225,114;6,107,549; 5,866,775; 5,804,425; 5,633,435; 5,463,175.

C. Waxy Starch

The waxy characteristic is an example of a recessive trait. In thisexample, the progeny resulting from the first backcross generation (BC1)must be grown and selfed. A test is then run on the selfed seed from theBC1 plant to determine which BC1 plants carried the recessive gene forthe waxy trait. In other recessive traits additional progeny testing,for example growing additional generations such as the BC1S1, may berequired to determine which plants carry the recessive gene.

D. Disease and Pest Resistance

Plant defenses are often activated by specific interaction between theproduct of a disease resistance gene (R) in the plant and the product ofa corresponding avirulence (Avr) gene in the pathogen. A plant line canbe transformed with cloned resistance gene to engineer plants that areresistant to specific pathogen strains. See, for example Jones et al.(Science, 266:7891, 1994) (cloning of the tomato Cf-9 gene forresistance to Cladosporium fulvum); Martin et al. (Science, 262: 1432,1993) (tomato Pto gene for resistance to Pseudomonas syringae pv.tomato); and Mindrinos et al., (Cell, 78(6):1089-1099, 1994)(Arabidopsis RPS2 gene for resistance to Pseudomonas syringae).

A viral-invasive protein or a complex toxin derived therefrom may alsobe used for viral disease resistance. For example, the accumulation ofviral coat proteins in transformed plant cells imparts resistance toviral infection and/or disease development effected by the virus fromwhich the coat protein gene is derived, as well as by related viruses.See Beachy et al., Ann. Rev. Phytopathol., 28:451, 1990. Coatprotein-mediated resistance has been conferred upon transformed plantsagainst alfalfa mosaic virus, cucumber mosaic virus, tobacco streakvirus, potato virus X, potato virus Y, tobacco etch virus, tobaccorattle virus and tobacco mosaic virus. Id.

A virus-specific antibody may also be used. See, for example,Tavladoraki et al. (Nature, 366:469, 1993), who show that transgenicplants expressing recombinant antibody genes are protected from virusattack. Virus resistance has also been described in, for example, U.S.Pat. Nos. 6,617,496; 6,608,241; 6,015,940; 6,013,864; 5,850,023 and5,304,730. Additional means of inducing whole-plant resistance to apathogen include modulation of the systemic acquired resistance (SAR) orpathogenesis related (PR) genes, for example genes homologous to theArabidopsis thaliana NIM1/NPR1/SAI1, and/or by increasing salicylic acidproduction (Ryals et al., Plant Cell, 8:1809-1819, 1996).

Logemann et al. (Biotechnology, 10:305, 1992), for example, disclosetransgenic plants expressing a barley ribosome-inactivating gene have anincreased resistance to fungal disease. Plant defensins may be used toprovide resistance to fungal pathogens (Thomma et al., Planta,216:193-202, 2002). Other examples of fungal disease resistance areprovided in U.S. Pat. Nos. 6,653,280; 6,573,361; 6,506,962; 6,316,407;6,215,048; 5,516,671; 5,773,696; 6,121,436; and 6,316,407.

Nematode resistance has been described, for example, in U.S. Pat. No.6,228,992 and bacterial disease resistance in U.S. Pat. No. 5,516,671.

E. Insect Resistance

One example of an insect resistance gene includes a Bacillusthuringiensis protein, a derivative thereof or a synthetic polypeptidemodeled thereon. See, for example, Geiser et al. (Gene, 48(1):109-118,1986), who disclose the cloning and nucleotide sequence of a Btδ-endotoxin gene. Moreover, DNA molecules encoding δ-endotoxin genes canbe purchased from the American Type Culture Collection, Manassas, Va.,for example, under ATCC Accession Nos. 40098, 67136, 31995 and 31998.Another example is a lectin. See, for example, Van Damme et al. (PlantMolec. Biol., 24:25, 1994), who disclose the nucleotide sequences ofseveral Clivia miniata mannose-binding lectin genes. A vitamin-bindingprotein may also be used, such as avidin. See PCT applicationUS93/06487, the contents of which are hereby incorporated by reference.This application teaches the use of avidin and avidin homologues aslarvicides against insect pests.

Yet another insect resistance gene is an enzyme inhibitor, for example,a protease or proteinase inhibitor or an amylase inhibitor. See, forexample, Abe et al., J. Biol. Chem., 262:16793, 1987 (nucleotidesequence of rice cysteine proteinase inhibitor); Huub et al., PlantMolec. Biol., 21:985, 1993 (nucleotide sequence of cDNA encoding tobaccoproteinase inhibitor I); and Sumitani et al., Biosci. Biotech. Biochem.,57:1243, 1993 (nucleotide sequence of Streptomyces nitrosporeusα-amylase inhibitor).

An insect-specific hormone or pheromone may also be used. See, forexample, the disclosure by Hammock et al. (Nature, 344:458, 1990), ofbaculovirus expression of cloned juvenile hormone esterase, aninactivator of juvenile hormone; Gade and Goldsworthy (Eds.Physiological System in Insects, Elsevier Academic Press, Burlington,Mass., 2007), describing allostatins and their potential use in pestcontrol; and Palli et al., Vitam. Horm., 73:59-100, 2005, disclosing useof ecdysteroid and ecdysteroid receptor in agriculture. The diuretichormone receptor (DHR) was identified in Price et al. (Insect Mol.Biol., 13:469-480, 2004) as a candidate target of insecticides.

Still other examples include an insect-specific antibody or animmunotoxin derived therefrom and a developmental-arrestive protein. SeeTaylor et al. (Seventh Int'l Symposium on Molecular Plant-MicrobeInteractions, Edinburgh, Scotland, Abstract W97, 1994), who describedenzymatic inactivation in transgenic tobacco via production ofsingle-chain antibody fragments. Numerous other examples of insectresistance have been described. See, for example, U.S. Pat. Nos.6,809,078; 6,713,063; 6,686,452; 6,657,046; 6,645,497; 6,642,030;6,639,054; 6,620,988; 6,593,293; 6,555,655; 6,538,109; 6,537,756;6,521,442; 6,501,009; 6,468,523; 6,326,351; 6,313,378; 6,284,949;6,281,016; 6,248,536; 6,242,241; 6,221,649; 6,177,615; 6,156,573;6,153,814; 6,110,464; 6,093,695; 6,063,756; 6,063,597; 6,023,013;5,959,091; 5,942,664; 5,942,658, 5,880,275; 5,763,245 and 5,763,241.

F. Modified Fatty Acid, Phytate and Carbohydrate Metabolism

Genes may be used conferring modified fatty acid metabolism, in terms ofcontent and quality. For example, stearyl-ACP desaturase genes may beused. See Knutzon et al., Proc. Natl. Acad. Sci. USA, 89:2624, 1992.Various fatty acid desaturases have also been described, such as aSaccharomyces cerevisiae OLE1 gene encoding Δ9-fatty acid desaturase, anenzyme which forms the monounsaturated palmitoleic (16:1) and oleic(18:1) fatty acids from palmitoyl (16:0) or stearoyl (18:0) CoA(McDonough et al., J. Biol. Chem., 267(9):5931-5936, 1992); a geneencoding a stearoyl-acyl carrier protein delta-9 desaturase from castor(Fox et al. Proc. Natl. Acad. Sci. USA, 90(6):2486-2490, 1993); Δ6- andΔ12-desaturases from the cyanobacteria Synechocystis responsible for theconversion of linoleic acid (18:2) to gamma-linolenic acid (18:3 gamma)(Reddy et al., Plant Mol. Biol., 22(2):293-300, 1993); a gene fromArabidopsis thaliana that encodes an omega-3 desaturase (Arondel et al.,Science, 258(5086):1353-1355 1992); plant Δ9-desaturases (PCTApplication Publ. No. WO 91/13972) and soybean and Brassica Δ15desaturases (European Patent Application Publ. No. EP 0616644).

Modified oils production is disclosed, for example, in U.S. Pat. Nos.6,444,876; 6,426,447 and 6,380,462. High oil production is disclosed,for example, in U.S. Pat. Nos. 6,495,739; 5,608,149; 6,483,008 and6,476,295. Modified fatty acid content is disclosed, for example, inU.S. Pat. Nos. 6,828,475; 6,822,141; 6,770,465; 6,706,950; 6,660,849;6,596,538; 6,589,767; 6,537,750; 6,489,461 and 6,459,018.

Phytate metabolism may also be modified by introduction of aphytase-encoding gene to enhance breakdown of phytate, adding more freephosphate to the transformed plant. For example, see Van Hartingsveldtet al., Gene, 127:87,1993, for a disclosure of the nucleotide sequenceof an Aspergillus niger phytase gene. In corn, this, for example, couldbe accomplished by cloning and then reintroducing DNA associated withthe single allele which is responsible for corn mutants characterized bylow levels of phytic acid. See Raboy et al., Plant Physiol.,124(1):355-368, 2000.

A number of genes are known that may be used to alter carbohydratemetabolism. For example, plants may be transformed with a gene codingfor an enzyme that alters the branching pattern of starch. See Shirozaet al., J. BacteoL., 170:810, 1988 (nucleotide sequence of Streptococcusmutans fructosyltransferase gene); Steinmetz et al., Mol. Gen. Genet.,20:220, 1985 (nucleotide sequence of Bacillus subtilis levansucrasegene); Pen et al., Biotechnology, 10:292, 1992 (production of transgenicplants that express Bacillus licheniformis α-amylase); U.S. Pat. No.6,166,292 (low raffinose); Elliot et al., Plant Molec. Biol., 21:515,1993 (nucleotide sequences of tomato invertase genes); Sergaard et al.,J. Biol. Chem., 268:22480, 1993 (site-directed mutagenesis of barleyα-amylase gene); Fisher et al., Plant Physiol., 102:1045, 1993 (maizeendosperm starch branching enzyme II); and U.S. Pat. Nos. 6,538,181;6,538,179; 6,538,178; 5,750,876 and 6,476,295 (starch content). The Z10gene encoding a 10 kD zein storage protein from maize may also be usedto alter the quantities of 10 kD zein in the cells relative to othercomponents (Kirihara et al., Gene, 71(2):359-370, 1988).

U.S. Patent Appl. Pub. No. 20030163838 describes maize cellulosesynthase genes and methods of use thereof.

G. Resistance to Abiotic Stress

Abiotic stress includes dehydration or other osmotic stress, salinity,high or low light intensity, high or low temperatures, submergence,exposure to heavy metals, and oxidative stress.Delta-pyrroline-5-carboxylate synthetase (P5CS) from mothbean has beenused to provide protection against general osmotic stress.Mannitol-1-phosphate dehydrogenase (mt1D) from E. coli has been used toprovide protection against drought and salinity. Choline oxidase (codAfrom Arthrobactor globiformis) can protect against cold and salt. E.coli choline dehydrogenase (betA) provides protection against salt.Additional protection from cold can be provided by omega-3-fatty aciddesaturase (fad7) from Arabidopsis thaliana. Trehalose-6-phosphatesynthase and levan sucrase (SacB) from yeast and Bacillus subtilis,respectively, can provide protection against drought (summarized fromAnnex II Genetic Engineering for Abiotic Stress Tolerance in Plants,Consultative Group On International Agricultural Research TechnicalAdvisory Committee). Overexpression of superoxide dismutase can be usedto protect against superoxides, as described in U.S. Pat. No. 5,538,878to Thomas et al.

H. Additional Traits

Additional traits can be introduced into the corn variety of the presentinvention. A non-limiting example of such a trait is a coding sequencewhich decreases RNA and/or protein levels. The decreased RNA and/orprotein levels may be achieved through RNAi methods, such as thosedescribed in U.S. Pat. No. 6,506,559 to Fire and Mellow.

Another trait that may find use with the corn variety of the inventionis a sequence which allows for site-specific recombination. Examples ofsuch sequences include the FRT sequence, used with the FLP recombinase(Zhu and Sadowski, J. Biol. Chem., 270:23044-23054, 1995); and the LOXsequence, used with CRE recombinase (Sauer, Mol. Cell. Biol.,7:2087-2096, 1987). The recombinase genes can be encoded at any locationwithin the genome of the corn plant, and are active in the hemizygousstate.

It may also be desirable to make corn plants more tolerant to or moreeasily transformed with Agrobacterium tumefaciens. Expression of p53 andiap, two baculovirus cell-death suppressor genes, inhibited tissuenecrosis and DNA cleavage. Additional targets can include plant-encodedproteins that interact with the Agrobacterium Vir genes; enzymesinvolved in plant cell wall formation; and histones, histoneacetyltransferases and histone deacetylases (reviewed in Gelvin,Microbiology & Mol. Biol. Reviews, 67:16-37, 2003).

In addition to the modification of oil, fatty acid or phytate contentdescribed above, it may additionally be beneficial to modify the amountsor levels of other compounds. For example, the amount or composition ofantioxidants can be altered. See, for example, U.S. Pat. No. 6,787,618,U.S. Patent Appl. Pub. No. 20040034886 and International Patent Appl.Pub. No. WO 00/68393, which disclose the manipulation of antioxidantlevels, and International Patent Appl. Pub. No. WO 03/082899, whichdiscloses the manipulation of a antioxidant biosynthetic pathway.

J. Illustrative Procedures for Introduction of a Desired Trait

As described above, techniques for the production of corn plants withadded traits are well known in the art (see, e.g., Poehlman et al., In:Breeding Field Crops, 4^(th) Ed., Iowa State University Press, Ames,Iowa, 132-155; 321-344, 1995; Fehr, Principles of Cultivar Development,1:360-376, 1987; Sprague and Dudley, In: Corn and Corn Improvement,3^(rd) Ed., Crop Science of America, Inc.; Soil Science of America,Inc., Wisconsin. 881-883; 901-918, 1988). A non-limiting example of sucha procedure one of skill in the art would use for preparation of a cornplant of CV951414 comprising an added trait is as follows:

-   -   (a) crossing corn plant CV951414 to a second (nonrecurrent) corn        plant comprising a locus to be converted in corn plant CV951414;    -   (b) selecting at least a first progeny plant resulting from the        crossing and comprising the locus;    -   (c) crossing the selected progeny to corn plant CV951414; and    -   (d) repeating steps (b) and (c) until a plant of variety        CV951414 is obtained comprising the locus.

Following these steps, essentially any locus may be introduced into cornvariety CV951414. For example, molecular techniques allow introductionof any given locus, without the need for phenotypic screening of progenyduring the backcrossing steps.

PCR and Southern hybridization are two examples of molecular techniquesthat may be used for confirmation of the presence of a given locus andthus conversion of that locus. The techniques are carried out asfollows: Seeds of progeny plants are grown and DNA isolated from leaftissue (see Sambrook et al., In: Molecular cloning, Cold Spring HarborLaboratory Press, Cold Spring Harbor, N.Y., 2001; Shure et al., Cell,35(1):225-233, 1983). Approximately one gram of leaf tissue islyophilized overnight in 15 ml polypropylene tubes. Freeze-dried tissueis ground to a powder in the tube using a glass rod. Powdered tissue ismixed thoroughly with 3 ml extraction buffer (7.0 M urea, 0.35 M NaCl,0.05 M Tris-HCl pH 8.0, 0.01 M EDTA, 1% sarcosine). Tissue/bufferhomogenate is extracted with 3 ml phenol/chloroform. The aqueous phaseis separated by centrifugation, and precipitated twice using 1/10 volumeof 4.4 M ammonium acetate pH 5.2, and an equal volume of isopropanol.The precipitate is washed with 75% ethanol and resuspended in 100-500 μlTE (0.01 M Tris-HCl, 0.001 M EDTA, pH 8.0). The DNA may then be screenedas desired for presence of the locus.

For PCR, two hundred to 1000 ng genomic DNA from the progeny plant beingscreened is added to a reaction mix containing 10 mM Tris-HCl pH 8.3,1.5 mM MgCl₂, 50 mM KCl, 0.1 mg/ml gelatin, 200 μM each dATP, dCTP,dGTP, dTTP, 20% glycerol, 2.5 units Taq DNA polymerase and 0.5 μM eachof forward and reverse DNA primers that span a segment of the locusbeing converted. The reaction is run in a thermal cycling machine 3minutes at 94 C, 39 repeats of the cycle 1 minute at 94 C, 1 minute at50 C, 30 seconds at 72 C, followed by 5 minutes at 72 C. Twenty μl ofeach reaction mix is run on a 3.5% NuSieve gel in TBE buffer (90 mMTris-borate, 2 mM EDTA) at 50V for two to four hours. The amplifiedfragment is detected using an agarose gel. Detection of an amplifiedfragment corresponding to the segment of the locus spanned by theprimers indicates the presence of the locus.

For Southern analysis, plant DNA is restricted, separated in an agarosegel and transferred to a Nylon filter in 10× SCP (20 SCP: 2M NaCl, 0.6 Mdisodium phosphate, 0.02 M disodium EDTA) according to standard methods(Southern, J. Mol. Biol., 98:503-517, 1975). Locus DNA or RNA sequencesare labeled, for example, radioactively with ³²P by random priming(Feinberg & Vogelstein, Anal. Biochem., 132(1):6-13, 1983). Filters areprehybridized in 6× SCP, 10% dextran sulfate, 2% sarcosine, and 500μg/ml denatured salmon sperm DNA. The labeled probe is denatured,hybridized to the filter and washed in 2× SCP, 1% SDS at 65° C. for 30minutes and visualized by autoradiography using Kodak XAR5 film.Presence of the locus is indicated by detection of restriction fragmentsof the appropriate size.

V. Tissue Cultures and In Vitro Regeneration of Corn Plants

A further aspect of the invention relates to tissue cultures of the cornplant designated CV951414. As used herein, the term “tissue culture”indicates a composition comprising isolated cells of the same or adifferent type or a collection of such cells organized into parts of aplant. Exemplary types of tissue cultures are protoplasts, calli andplant cells that are intact in plants or parts of plants, such asembryos, pollen, flowers, kernels, ears, cobs, leaves, husks, stalks,roots, root tips, anthers, silk, and the like. In a preferredembodiment, the tissue culture comprises embryos, protoplasts,meristematic cells, pollen, leaves or anthers derived from immaturetissues of these plant parts. Means for preparing and maintaining planttissue cultures are well known in the art (U.S. Pat. Nos. 5,538,880; and5,550,318, each incorporated herein by reference in their entirety). Byway of example, a tissue culture comprising organs such as tassels oranthers has been used to produce regenerated plants (U.S. Pat. Nos.5,445,961 and 5,322,789; the disclosures of which are incorporatedherein by reference).

One type of tissue culture is tassel/anther culture. Tassels containanthers which in turn enclose microspores. Microspores develop intopollen. For anther/microspore culture, if tassels are the plantcomposition, they are preferably selected at a stage when themicrospores are uninucleate, that is, include only one, rather than 2 or3 nuclei. Methods to determine the correct stage are well known to thoseskilled in the art and include mitramycin fluorescent staining (Pace etal., Theoretical and Applied Genetics, 73:863-869, 1987), trypan blue(preferred) and acetocarmine squashing. The mid-uninucleate microsporestage has been found to be the developmental stage most responsive tothe subsequent methods disclosed to ultimately produce plants.

Although microspore-containing plant organs such as tassels cangenerally be pretreated at any cold temperature below about 25° C., arange of 4 to 25° C. is preferred, and a range of 8 to 14° C. isparticularly preferred. Although other temperatures yield embryoids andregenerated plants, cold temperatures produce optimum response ratescompared to pretreatment at temperatures outside the preferred range.Response rate is measured as either the number of embryoids or thenumber of regenerated plants per number of microspores initiated inculture. Exemplary methods of microspore culture are disclosed in, forexample, Gaillard et al., Plant Cell Reports, 10(2):55, 1991, and U.S.Pat. Nos. 5,322,789 and 5,445,961, the disclosures of which arespecifically incorporated herein by reference.

Although not required, when tassels are employed as the plant organ, itis generally preferred to sterilize their surface. Following surfacesterilization of the tassels, for example, with a solution of calciumhypochloride, the anthers are removed from about 70 to 150 spikelets(small portions of the tassels) and placed in a preculture orpretreatment medium. Larger or smaller amounts can be used depending onthe number of anthers.

When one elects to employ tassels directly, tassels are preferablypretreated at a cold temperature for a predefined time, preferably at10° C. for about 4 days. After pretreatment of a whole tassel at a coldtemperature, dissected anthers are further pretreated in an environmentthat diverts microspores from their developmental pathway. The functionof the preculture medium is to switch the developmental program from oneof pollen development to that of embryoid/callus development. Anembodiment of such an environment in the form of a preculture mediumincludes a sugar alcohol, for example mannitol or sorbitol, inositol orthe like. An exemplary synergistic combination is the use of mannitol ata temperature of about 10° C. for a period ranging from about 10 to 14days. In a preferred embodiment, 3 ml of 0.3 M mannitol combined with 50mg/l of ascorbic acid, silver nitrate, and colchicine is used forincubation of anthers at 10° C. for between 10 and 14 days. Anotherembodiment is to substitute sorbitol for mannitol. The colchicineproduces chromosome doubling at this early stage. The chromosomedoubling agent is preferably only present at the preculture stage.

It is believed that the mannitol or other similar carbon structure orenvironmental stress induces starvation and functions to forcemicrospores to focus their energies on entering developmental stages.The cells are unable to use, for example, mannitol as a carbon source atthis stage. It is believed that these treatments confuse the cellscausing them to develop as embryoids and plants from microspores.Dramatic increases in development from these haploid cells, as high as25 embryoids in 10⁴ microspores, have resulted from using these methods.

To isolate microspores, an isolation media is preferred. An isolationmedia is used to separate microspores from the anther walls whilemaintaining their viability and embryogenic potential. An illustrativeembodiment of an isolation media includes a 6% sucrose or maltosesolution combined with an antioxidant such as 50 mg/l of ascorbic acid,0.1 mg/l biotin, and 400 mg/l of proline, combined with 10 mg/l ofnicotinic acid and 0.5 mg/l AgNO₃. In another embodiment, the biotin andproline are omitted.

An isolation media preferably has a higher antioxidant level where it isused to isolate microspores from a donor plant (a plant from which aplant composition containing a microspore is obtained) that is fieldgrown in contrast to greenhouse grown. A preferred level of ascorbicacid in an isolation medium is from about 50 mg/l to about 125 mg/l and,more preferably, from about 50 mg/l to about 100 mg/l.

One can find particular benefit in employing a support for themicrospores during culturing and subculturing. Any support thatmaintains the cells near the surface can be used. An illustrativeembodiment of a solid support is a TRANSWELL® culture dish. Anotherembodiment of a solid support for development of the microspores is abilayer plate wherein liquid media is on top of a solid base. Otherembodiments include a mesh or a millipore filter. Preferably, a solidsupport is a nylon mesh in the shape of a raft. A raft is defined as anapproximately circular support material which is capable of floatingslightly above the bottom of a tissue culture vessel, for example, apetri dish, of about a 60 or 100 mm size, although any other laboratorytissue culture vessel will suffice. In an illustrative embodiment, araft is about 55 mm in diameter.

Culturing isolated microspores on a solid support, for example, on a 10mm pore nylon raft floating on 2.2 ml of medium in a 60 mm petri dish,prevents microspores from sinking into the liquid medium and thusavoiding low oxygen tension. These types of cell supports enable theserial transfer of the nylon raft with its associatedmicrospore/embryoids ultimately to full strength medium containingactivated charcoal and solidified with, for example, GELRITE™(solidifying agent).

The liquid medium passes through the mesh while the microspores areretained and supported at the medium-air interface. The surface tensionof the liquid medium in the petri dish causes the raft to float. Theliquid is able to pass through the mesh; consequently, the microsporesstay on top. The mesh remains on top of the total volume of liquidmedium.

The culture vessels can be further defined as either (1) a bilayer 60 mmpetri plate wherein the bottom 2 ml of medium are solidified with 0.7%agarose overlaid with 1 mm of liquid containing the microspores; (2) anylon mesh raft wherein a wafer of nylon is floated on 1.2 ml of mediumand 1 ml of isolated microspores is pipetted on top; or (3) TRANSWELL®plates wherein isolated microspores are pipetted onto membrane insertswhich support the microspores at the surface of 2 ml of medium.

Examples of processes of tissue culturing and regeneration of corn aredescribed in, for example, European Patent Application 0 160 390, Greenand Rhodes, Maize for Biological Research, 367-372, 1982; and Duncan etal., Planta, 165:322-332, 1985; Songstad et al., Plant Cell Reports,7:262-265, 1988; Rao et al., In: Somatic Embryogenesis in Glume CallusCultures, Maize Genetics Cooperation Newsletter #60, 1986; Conger etal., Plant Cell Reports, 6:345-347, 1987; PCT Application WO 95/06128,Armstrong and Green, Planta, 164:207-214, 1985; Gordon-Kamm et al., ThePlant Cell, 2:603-618, 1990; Gaillard et al., Plant Cell Reports,10(2):55, 1991; and U.S. Pat. No. 5,736,369.

VI. Process of Crossing Corn Plants and the Corn Plants Produced by suchCrosses

The present invention provides processes of preparing novel corn plantsand corn plants produced by such processes. In accordance with such aprocess, a first parent corn plant may be crossed with a second parentcorn plant wherein at least one of the first and second corn plants isthe inbred corn plant CV951414. One application of the process is in theproduction of F₁ hybrid plants. Another important aspect of this processis that it can be used for the development of novel inbred lines. Forexample, the inbred corn plant CV951414 could be crossed to any secondplant, and the resulting hybrid progeny each selfed for about 5 to 7 ormore generations, thereby providing a large number of distinct,pure-breeding inbred lines. These inbred lines could then be crossedwith other inbred or non-inbred lines and the resulting hybrid progenyanalyzed for beneficial characteristics. In this way, novel inbred linesconferring desirable characteristics could be identified.

Corn plants (Zea mays L.) can be crossed by either natural or mechanicaltechniques. Natural pollination occurs in corn when wind blows pollenfrom the tassels to the silks that protrude from the tops of therecipient ears. Mechanical pollination can be effected either bycontrolling the types of pollen that can blow onto the silks or bypollinating by hand. In one embodiment, crossing comprises the steps of:

-   -   (a) planting in pollinating proximity seeds of a first and a        second parent corn plant, and preferably, seeds of a first        inbred corn plant and a second, distinct inbred corn plant;    -   (b) cultivating or growing the seeds of the first and second        parent corn plants into plants that bear flowers;    -   (c) emasculating flowers of either the first or second parent        corn plant, i.e., treating the flowers so as to prevent pollen        production, or alternatively, using as the female parent a male        sterile plant, thereby providing an emasculated parent corn        plant;    -   (d) allowing natural cross-pollination to occur between the        first and second parent corn plants;    -   (e) harvesting seeds produced on the emasculated parent corn        plant; and, where desired,    -   (f) growing the harvested seed into a corn plant, preferably, a        hybrid corn plant.

Parental plants are typically planted in pollinating proximity to eachother by planting the parental plants in alternating rows, in blocks orin any other convenient planting pattern. Where the parental plantsdiffer in timing of sexual maturity, it may be desired to plant theslower maturing plant first, thereby ensuring the availability of pollenfrom the male parent during the time at which silks on the female parentare receptive to pollen. Plants of both parental parents are cultivatedand allowed to grow until the time of flowering. Advantageously, duringthis growth stage, plants are in general treated with fertilizer and/orother agricultural chemicals as considered appropriate by the grower.

At the time of flowering, in the event that plant CV951414 is employedas the male parent, the tassels of the other parental plant are removedfrom all plants employed as the female parental plant to avoidself-pollination. The detasseling can be achieved manually but also canbe done by machine, if desired. Alternatively, when the female parentcorn plant comprises a cytoplasmic or nuclear gene conferring malesterility, detasseling may not be required. Additionally, a chemicalgametocide may be used to sterilize the male flowers of the femaleplant. In this case, the parent plants used as the male may either notbe treated with the chemical agent or may comprise a genetic factorwhich causes resistance to the emasculating effects of the chemicalagent. Gametocides affect processes or cells involved in thedevelopment, maturation or release of pollen. Plants treated with suchgametocides are rendered male sterile, but typically remain femalefertile. The use of chemical gametocides is described, for example, inU.S. Pat. No. 4,936,904, the disclosure of which is specificallyincorporated herein by reference in its entirety. Furthermore, the useof glyphosate herbicide to produce male sterile corn plants is disclosedin U.S. Pat. No. 6,762,344 and PCT Publication WO 98/44140.

Following emasculation, the plants are then typically allowed tocontinue to grow and natural cross-pollination occurs as a result of theaction of wind, which is normal in the pollination of grasses, includingcorn. As a result of the emasculation of the female parent plant, allthe pollen from the male parent plant is available for pollinationbecause tassels, and thereby pollen bearing flowering parts, have beenpreviously removed from all plants of the inbred plant being used as thefemale in the hybridization. Of course, during this hybridizationprocedure, the parental varieties are grown such that they are isolatedfrom other corn fields to minimize or prevent any accidentalcontamination of pollen from foreign sources. These isolation techniquesare well within the skill of those skilled in this art.

Both parental inbred plants of corn may be allowed to continue to growuntil maturity or the male rows may be destroyed after flowering iscomplete. Only the ears from the female inbred parental plants areharvested to obtain seeds of a novel F₁ hybrid. The novel F₁ hybrid seedproduced can then be planted in a subsequent growing season incommercial fields or, alternatively, advanced in breeding protocols forpurposes of developing novel inbred lines.

Alternatively, in another embodiment of the invention, both first andsecond parent corn plants can be from variety CV951414. Thus, any cornplant produced using corn plant CV951414 forms a part of the invention.As used herein, crossing can mean selfing, backcrossing, crossing toanother or the same inbred, crossing to populations, and the like. Allcorn plants produced using the inbred corn plant CV951414 as a parentare, therefore, within the scope of this invention.

A. F₁ Hybrid Corn Plant and Seed Production

One beneficial use of the instant corn variety is in the production ofhybrid seed. Any time the inbred corn plant CV951414 is crossed withanother, different, corn inbred, a first generation (F₁) corn hybridplant is produced. As such, an F₁ hybrid corn plant can be produced bycrossing CV951414 with any second inbred maize plant. Essentially anyother corn plant can be used to produce a hybrid corn plant having cornplant CV951414 as one parent. All that is required is that the secondplant be fertile, which corn plants naturally are, and that the plant isnot corn variety CV951414.

The goal of the process of producing an F₁ hybrid is to manipulate thegenetic complement of corn to generate new combinations of genes whichinteract to yield new or improved traits (phenotypic characteristics). Aprocess of producing an F₁ hybrid typically begins with the productionof one or more inbred plants. Those plants are produced by repeatedcrossing of ancestrally related corn plants to try to combine certaingenes within the inbred plants.

Corn has a diploid phase which means two conditions of a gene (twoalleles) occupy each locus (position on a chromosome). If the allelesare the same at a locus, there is said to be homozygosity. If they aredifferent, there is said to be heterozygosity. In a completely inbredplant, all loci are homozygous. Because many loci when homozygous aredeleterious to the plant, in particular leading to reduced vigor, lesskernels, weak and/or poor growth, production of inbred plants is anunpredictable and arduous process. Under some conditions, heterozygousadvantage at some loci effectively bars perpetuation of homozygosity.

A single cross hybrid corn variety is the cross of two inbred plants,each of which has a genotype which complements the genotype of theother. Typically, F₁ hybrids are more vigorous than their inbredparents. This hybrid vigor, or heterosis, is manifested in manypolygenic traits, including markedly improved yields, better stalks,better roots, better uniformity and better insect and diseaseresistance. In the development of hybrids only the F₁ hybrid plants aretypically sought. An F₁ single cross hybrid is produced when two inbredplants are crossed. A double cross hybrid is produced from four inbredplants crossed in pairs (A×B and C×D) and then the two F₁ hybrids arecrossed again (A×B)×(C×D).

Thousands of corn varieties are known to those of skill in the art, anyone of which could be crossed with corn plant CV951414 to produce ahybrid plant. For example, the U.S. Patent & Trademark Office has issuedmore than 300 utility patents for corn varieties. Estimates place thenumber of different corn accessions in genebanks around the world ataround 50,000 (Chang, In Plant Breeding in the 1990s, Stalker and Murphy(Eds.), Wallingford, U.K., CAB International, 17-35, 1992). The MaizeGenetics Cooperation Stock Center, which is supported by the U.S.Department of Agriculture, has a total collection approaching 80,000individually pedigreed samples (www. maizecoop.cropsci.uiuc.edu/).

An example of an F₁ hybrid which has been produced with CV951414 as aparent is the hybrid CH227660. Hybrid CH227660 was produced by crossinginbred corn plant CV951414 with the inbred corn plant designatedCV468110 (U.S. patent application Ser. No. 12/411,361, the disclosure ofwhich is specifically incorporated herein by reference in its entirety).

When the inbred corn plant CV951414 is crossed with another inbred plantto yield a hybrid, it can serve as either the maternal or paternalplant. For many crosses, the outcome is the same regardless of theassigned sex of the parental plants. Depending on the seed productioncharacteristics relative to a second parent in a hybrid cross, it may bedesired to use one of the parental plants as the male or female parent.Some plants produce tighter ear husks leading to more loss, for exampledue to rot. There can be delays in silk formation which deleteriouslyaffect timing of the reproductive cycle for a pair of parental plants.Seed coat characteristics can be preferable in one plant. Pollen can beshed better by one plant. Therefore, a decision to use one parent plantas a male or female may be made based on any such characteristics as iswell known to those of skill in the art.

B. Development of Corn Varieties

The development of new varieties using one or more starting varieties iswell known in the art. In accordance with the invention, novel varietiesmay be created by crossing corn variety CV951414 followed by multiplegenerations of breeding according to such well known methods. Newvarieties may be created by crossing corn variety CV951414 with anysecond plant. In selecting such a second plant to cross for the purposeof developing novel inbred lines, it may be desired to choose thoseplants which either themselves exhibit one or more selected desirablecharacteristics or which exhibit the desired characteristic(s) when inhybrid combination. Examples of potentially desired characteristicsinclude greater yield, better stalks, better roots, resistance toinsecticides, herbicides, pests, and disease, tolerance to heat anddrought, reduced time to crop maturity, better agronomic quality, highernutritional value, and uniformity in germination times, standestablishment, growth rate, maturity, and fruit size.

Once initial crosses have been made with corn variety CV951414,inbreeding takes place to produce new inbred varieties. Inbreedingrequires manipulation by human breeders. Even in the extremely unlikelyevent inbreeding rather than crossbreeding occurred in natural corn,achievement of complete inbreeding cannot be expected in nature due towell known deleterious effects of homozygosity and the large number ofgenerations the plant would have to breed in isolation. The reason forthe breeder to create inbred plants is to have a known reservoir ofgenes whose gametic transmission is predictable.

The pedigree breeding method involves crossing two genotypes. Eachgenotype can have one or more desirable characteristics lacking in theother; or, each genotype can complement the other. If the two originalparental genotypes do not provide all of the desired characteristics,other genotypes can be included in the breeding population. Superiorplants that are the products of these crosses are selfed and selected insuccessive generations. Each succeeding generation becomes morehomogeneous as a result of self-pollination and selection. Typically,this method of breeding involves five or more generations of selfing andselection: S₁→S₂; S₂→S₃; S₃→S₄; S₄→S₅, etc. After at least fivegenerations, the inbred plant is considered genetically pure.

Backcrossing can also be used to improve an inbred plant. Backcrossingtransfers a specific desirable trait from one inbred or non-inbredsource to an inbred that lacks that trait. This can be accomplished, forexample, by first crossing a superior inbred (A) (recurrent parent) to adonor inbred (non-recurrent parent), which carries the appropriate locusor loci for the trait in question. The progeny of this cross are thenmated back to the superior recurrent parent (A) followed by selection inthe resultant progeny for the desired trait to be transferred from thenon-recurrent parent. After five or more backcross generations withselection for the desired trait, the progeny are heterozygous for locicontrolling the characteristic being transferred, but are like thesuperior parent for most or almost all other loci. The last backcrossgeneration would be selfed to give pure breeding progeny for the traitbeing transferred.

The development of a hybrid corn variety involves three steps: (1) theselection of plants from various germplasm pools; (2) the selfing of theselected plants for several generations to produce a series of inbredplants, which, although different from each other, each breed true andare highly uniform; and (3) crossing the selected inbred plants withunrelated inbred plants to produce the hybrid progeny (F₁). During theinbreeding process in corn, the vigor of the plants decreases. Vigor isrestored when two unrelated inbred plants are crossed to produce thehybrid progeny (F₁). An important consequence of the homozygosity andhomogeneity of the inbred plants is that the hybrid between any twoinbreds is always the same. Once the inbreds that give a superior hybridhave been identified, hybrid seed can be reproduced indefinitely as longas the homogeneity of the inbred parents is maintained. Conversely, muchof the hybrid vigor exhibited by F₁ hybrids is lost in the nextgeneration (F₂). Consequently, seed from hybrid varieties is not usedfor planting stock. It is not generally beneficial for farmers to saveseed of F₁ hybrids. Rather, farmers purchase F₁ hybrid seed for plantingevery year.

The development of inbred plants generally requires at least about 5 to7 generations of selfing. Inbred plants are then cross-bred in anattempt to develop improved F₁ hybrids. Hybrids are then screened andevaluated in small scale field trials. Typically, about 10 to 15phenotypic traits, selected for their potential commercial value, aremeasured. A selection index of the most commercially important traits isused to help evaluate hybrids. FACT, an acronym for Field AnalysisComparison Trial (strip trials), is an on-farm experimental testingprogram employed by Monsanto Company to perform the final evaluation ofthe commercial potential of a product.

During the next several years, a progressive elimination of hybridsoccurs based on more detailed evaluation of their phenotype. Eventually,strip trials (FACT) are conducted to formally compare the experimentalhybrids being developed with other hybrids, some of which werepreviously developed and generally are commercially successful. That is,comparisons of experimental hybrids are made to competitive hybrids todetermine if there was any advantage to further development of theexperimental hybrids. Examples of such comparisons are presented hereinbelow. After FACT testing is complete, determinations may be madewhether commercial development should proceed for a given hybrid.

C. F₁ Hybrid Comparisons

As mentioned above, hybrids are progressively eliminated followingdetailed evaluations of their phenotype, including formal comparisonswith other commercially successful hybrids. Strip trials are used tocompare the phenotypes of hybrids grown in as many environments aspossible. They are performed in many environments to assess overallperformance of the new hybrids and to select optimum growing conditions.Because the corn is grown in close proximity, environmental factors thataffect gene expression, such as moisture, temperature, sunlight, andpests, are minimized. For a decision to be made to commercialize ahybrid, it is not necessary that the hybrid be better than all otherhybrids. Rather, significant improvements must be shown in at least sometraits that would create improvements in some niches.

Examples of such comparative data are set forth herein below in Table 2,which presents a comparison of performance data for a hybrid made withCV951414 as one parent, versus selected hybrids of commercial value.

The present invention provides a genetic complement of the inbred cornplant variety designated CV951414. Further provided by the invention isa hybrid genetic complement, wherein the complement is formed by thecombination of a haploid genetic complement from CV951414 and anotherhaploid genetic complement. Means for determining such a geneticcomplement are well-known in the art.

As used herein, the phrase “genetic complement” means an aggregate ofnucleotide sequences, the expression of which defines the phenotype of acorn plant or a cell or tissue of that plant. By way of example, a cornplant is genotyped to determine a representative sample of the inheritedmarkers it possesses. Markers are alleles at a single locus. They arepreferably inherited in codominant fashion so that the presence of bothalleles at a diploid locus is readily detectable, and they are free ofenvironmental variation, i.e., their heritability is 1. This genotypingis preferably performed on at least one generation of the descendantplant for which the numerical value of the quantitative trait or traitsof interest are also determined. The array of single locus genotypes isexpressed as a profile of marker alleles, two at each locus. The markerallelic composition of each locus can be either homozygous orheterozygous. Homozygosity is a condition where both alleles at a locusare characterized by the same nucleotide sequence or size of a repeatedsequence. Heterozygosity refers to different conditions of the gene at alocus. A preferred type of genetic marker for use with the invention issimple sequence repeats (SSRs), although potentially any other type ofgenetic marker could be used, for example, restriction fragment lengthpolymorphisms (RFLPs), amplified fragment length polymorphisms (AFLPs),single nucleotide polymorphisms (SNPs), and isozymes.

A genetic marker profile of an inbred may be predictive of the agronomictraits of a hybrid produced using that inbred. For example, if an inbredof known genetic marker profile and phenotype is crossed with a secondinbred of known genetic marker profile and phenotype it is possible topredict the phenotype of the F₁ hybrid based on the combined geneticmarker profiles of the parent inbreds. Methods for prediction of hybridperformance from genetic marker data is disclosed in U.S. Pat. No.5,492,547, the disclosure of which is specifically incorporated hereinby reference in its entirety. Such predictions may be made using anysuitable genetic marker, for example, SSRs, RFLPs, AFLPs, SNPs, orisozymes.

SSRs are genetic markers based on polymorphisms in repeated nucleotidesequences, such as microsatellites. A marker system based on SSRs can behighly informative in linkage analysis relative to other marker systemsin that multiple alleles may be present. Another advantage of this typeof marker is that, through use of flanking primers, detection of SSRscan be achieved, for example, by the polymerase chain reaction (PCR™),thereby eliminating the need for labor-intensive Southern hybridization.The PCR™ detection is done by use of two oligonucleotide primersflanking the polymorphic segment of repetitive DNA. Repeated cycles ofheat denaturation of the DNA followed by annealing of the primers totheir complementary sequences at low temperatures, and extension of theannealed primers with DNA polymerase, comprise the major part of themethodology. Following amplification, markers can be scored by gelelectrophoresis of the amplification products. Scoring of markergenotype is based on the size (number of base pairs) of the amplifiedsegment.
